ASTM A312 TP Stainless Steel 316H Welded Pipes exhibit non-hardenable characteristics, being magnetic when cold-worked to some extent, and non-magnetic in the annealed form. These pipes utilize nickel to maintain a primary solid solution composition at lower temperatures, making them suitable for fastening applications due to their lower carbon content compared to Stainless Steel 301 Pipes to Stainless Steel 303 Pipes, thus avoiding inorganic compound precipitation. The higher carbon content of this material contributes to excellent yielding and high tensile strength, while the austenitic structure provides remarkable hardness at low or cryogenic temperatures. Metinox Overseas' Stainless Steel ASTM A312 TP 316H Welded Pipes offer improved corrosion resistance to chlorides and are susceptible to chloride stress corrosion cracking. They are recommended for use in applications where exposure in the carbide precipitation range is unavoidable and where annealing after welding is not practical.
